[S390] cio: kernel stack overflow.
Use different kind of assignment to make sure gcc doesn't create code that creates temp variables on the stack, assigns values to it and copies the content of the whole temp variable to the destination. This reduces stack usage of e.g. ccwgroup_driver_register from 976 to 48 bytes instead.
